I have a 1gb nvidia 9500 gt graphics card. when i was using xp then it was showing that my 9500gt has 1gb ram. but recently i am using windows 7 ultimate and now windows 7 is showing that my graphics card has 1779mb ram. 1gb ram in graphics card and 755mb ram is sharing from system memory. my question is that my nvidia 9500gt can not share ram from system memory but how in windows 7 it can shre ram from system memory? Is it good for my hardwares? plz help me ........................
